Generate <img src="https://mermaid.js.org/favicon.svg" height="14"/> [mermaid](https://mermaid.js.org/) diagram and chart with AI MCP dynamically. Also you can use:

- <img src="https://mdn.alipayobjects.com/huamei_qa8qxu/afts/img/A*ZFK8SrovcqgAAAAAAAAAAAAAemJ7AQ/original" height="14"/> [mcp-server-chart](https://github.com/antvis/mcp-server-chart) to generate chart, graph, map.
- <img src="https://mdn.alipayobjects.com/huamei_qa8qxu/afts/img/A*EdkXSojOxqsAAAAAQHAAAAgAemJ7AQ/original" height="14"/> [Infographic](https://github.com/antvis/Infographic) to generate infographic, such as `Timeline`, `Comparison`, `List`, `Process` and so on.
- 🖼️ [figure.ling.pub/gallery](https://figure.ling.pub/gallery) to browse and share AI-generated diagrams and figures created with mcp-mermaid and other tools.


## ✨ Features

- Fully support all features and syntax of `Mermaid`.
- Support configuration of `backgroundColor` and `theme`, enabling large AI models to output rich style configurations.

- Support exporting to `base64`, `svg`, `mermaid`, `file`, and remote-friendly `svg_url`, `png_url` formats, with validation for `Mermaid` to facilitate the model's multi-round output of correct syntax and graphics. Use `outputType: "file"` to automatically save PNG diagrams to disk for AI agents, or the URL modes to share diagrams through public mermaid.ink links.

## 🤖 Usage

To use with `Desktop APP`, such as Claude, VSCode, Cline, Cherry Studio, and so on, add the  MCP server config below. On Mac system:

```json
{
  "mcpServers": {
    "mcp-mermaid": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-mermaid"
      ]
    }
  }
}
```

On Window system:

```json
{
  "mcpServers": {
    "mcp-mermaid": {
      "command": "cmd",
      "args": [
        "/c",
        "npx",
        "-y",
        "mcp-mermaid"
      ]
    }
  }
}
```

Also, you can use it on aliyun, modelscope, glama.ai, smithery.ai or others with HTTP, SSE Protocol.

**Access Points:**
- SSE: `http://localhost:3033/sse`
- Streamable: `http://localhost:1122/mcp`

**Available Docker Tags:**
- `susuperli/mcp-mermaid:latest` - Latest stable version
- View all available tags at [Docker Hub](https://hub.docker.com/repository/docker/susuperli/mcp-mermaid/tags)


## 🚰 Run with SSE or Streamable transport

### Option 1: Global Installation

Install the package globally:

```bash
npm install -g mcp-mermaid
```

Run the server with your preferred transport option:

```bash
# For SSE transport (default endpoint: /sse)
mcp-mermaid -t sse

# For Streamable transport with custom endpoint
mcp-mermaid -t streamable
```

### Option 2: Local Development

If you're working with the source code locally:

```bash
# Clone and setup
git clone https://github.com/hustcc/mcp-mermaid.git
cd mcp-mermaid
npm install
npm run build

# Run with npm scripts
npm run start:sse        # SSE transport on port 3033
npm run start:streamable # Streamable transport on port 1122
```

### Access Points

Then you can access the server at:

- SSE transport: `http://localhost:3033/sse`
- Streamable transport: `http://localhost:1122/mcp` (local) or `http://localhost:3033/mcp` (global)

## 🎮 CLI Options

You can also use the following CLI options when running the MCP server. Command options by run cli with `-h`.

```plain
MCP Mermaid CLI

Options:
  --transport, -t  Specify the transport protocol: "stdio", "sse", or "streamable" (default: "stdio")
  --port, -p       Specify the port for SSE or streamable transport (default: 3033)
  --endpoint, -e   Specify the endpoint for the transport:
                    - For SSE: default is "/sse"
                    - For streamable: default is "/mcp"
  --help, -h       Show this help message
```

## 🔨 Development

Install dependencies:

```bash
npm install
```

Build the server:

```bash
npm run build
```

### Start the MCP server

**Using MCP Inspector (for debugging):**

```bash
npm run start
```

**Using different transport protocols:**

```bash
# SSE transport (Server-Sent Events)
npm run start:sse

# Streamable HTTP transport
npm run start:streamable
```

**Direct node commands:**

```bash
# SSE transport on port 3033
node build/index.js --transport sse --port 3033

# Streamable HTTP transport on port 1122
node build/index.js --transport streamable --port 1122

# STDIO transport (for MCP client integration)
node build/index.js --transport stdio
```

## 🐳 Docker Usage

Run MCP Mermaid with Docker:

```bash
# Pull the image
docker pull susuperli/mcp-mermaid:latest

# Run with SSE transport (default)
docker run -p 3033:3033 susuperli/mcp-mermaid:latest --transport sse

# Run with streamable transport
docker run -p 1122:1122 susuperli/mcp-mermaid:latest --transport streamable --port 1122
```
